Campylomyza lapponica Jaschhof 2015, spec. nov.

Campylomyza lapponica spec. nov.

(Figs 8–9)

Diagnostic description: Many of the diagnostic characters used in the serrata group are especially pronounced in Campylomyza lapponica. The medial gonocoxal bridges, which strongly project both posteriorly (←) and dorsomedially (←), have conspicuously large microtrichia (Fig. 8); the dorsal gonocoxal bridge is very narrow and strongly projects anteriorly (←, Fig. 8); the gonostyli are strongly convex posteriorly (←) and strongly excavated ventromedially (Fig. 8); the tegminal shoulders are distinct (←) and the tegminal processes are of considerable length (Fig. 9). While the gonostyli in the other species of the serrata group are thick, especially in the lobe-bearers, those of C. lapponica are laterally compressed–a peculiarity not apparent in Figure 8. Other diagnostic characters of this species are as follows. The ninth tergite is narrow (Fig. 8). The ventral emargination of the gonocoxites is moderately deep (i.e. the ventral bridge is rather long) and reinforced by a broad, bare sclerotized rim basally (Fig. 8). The parameral apodemes are short (Fig. 9). The aedeagal head is medium-sized (Fig. 8).

Etymology: The Latin adjective lapponica refers to the distribution of this species in Lapland (lat. Lapponia).
